(c1. zar-15o) This invention has relevance to improved capstan or like hauling means for raising or lowering anchors, nets, or other articles or constructions.

Said improved capstan or like hauling means comprise a suitably journalled spindle. Upon the latter is loosely mounted a rotatable rope carrying barrel; in the circumferential wall of the barrel are two or more spaced recesses to receive a tommy bar, and also on the bottom face of the barrel are two or more spaced dowels adapted to cooperatively engage recesses in the upper face of a gipsy wheel which also is loosely mounted on said spindle below said barrel. A fixed collar is associated with the spindle below said wheel. A ratchet wheel can be mounted on the upper portion of said spindle, and a spring controlled pawl is associated with the said barrel and is adjustable for relative cooperative action with said ratchet wheel A tapped cap with ilat bottom face is adapted to cooperate with a flat upper face on said barrel, the said cap having two or more recesses in its circumferential wall adapted to receive a tommy bar. Said cap is also adapted to iit the externally screw-threaded upper end of said spindle. All of the said elements are arranged for operation With or without power drive means for the purposes and in the manner hereinafter referred to.

The said spindle may be adjustably couplable to another spindle, the latter spindle having associated therewith gear drive means couplably associated with power drive means.

Further, the pawl and its control spring can be carried in a recess in the circumferential wall of the barrel, the pawl being carried on one end of a spindle whose other end carries a `ringer knob externally of said wall. The barrel also has in its said wall two spaced openings adapted to be engaged by a pin projecting from said knob, so that the rotational direction of the ratchet wheel can be altered, or whereby when said pin is made to engage the exterior of said circumferential wall the said pawl will be kept out of engagement with said ratchet wheel.

Other features of the invention are hereinafter referred to in the fuller description of the invention made with reference to the accompanying drawing, in which: Fig. 1 is a perspective view of capstan means according to the invention and adapted to be driven either manually o1` by power; Fig. 2 is a central sectional elevation thereof; Fig. 3 is a sectional plan on line 3-3 of Fig. 2; Fig. 4 is a detail sectional View; Fig. 5 is a sectional plan on line 5-5 of Fig. 2; and Fig. 6 is an elevation of capstan means constructed for manual operation.

The spindle I of thecapstan is vertically disposed and has a fixed collar 2 upon which is adapted to rest a gipsy wheel 3 which is loosely mounted on the spindle I. The winding barrel 4 is adapted to cooperate with the gipsy wheel 3, the barrel I being also loosely mounted on the spindle I; in the bottom face of the barrel 4 are two or more spaced vertically disposed dcwel pins 5. DoWel pins 5 can enter recesses t in the upper face of the gipsy wheel 3 Whereby the latter and the winding barrel 4 are cooperatively connected to be rotated simultaneously. In the head of the barrel 4 is a recess I in which can be accommodated a ratchet wheel 8 of suitable design. Wheel 8 can be loosely mounted on a rectangular boss 9 near the upper 'end of the spindle I.

A spring loaded pawl Ii can be made to engage with the ratchet wheel 8, or pawl IE) can be held out of engagement with the wheel 8; the pawl I0 is slidable horizontally within a recess II in the circumferential wall of the head of the winding barrel 4. The pawl It) is secured on the inner end of a spindle I2; the latter is slidable in a bearing I4 therefor in the barrel 4;l

its outer end is tted with a manually operable knob I5 which projects beyond the said wall of the head ofthe barrel 4. Knob I5 can carry a projecting pin II which can be made to engage a pair of diametrically disposed recesses .I8 in the circumferential wall of the head of the barrel Il. Through operation of the pawl Ill for engagement with the respective recesses I8, the said pawl can be altered in relation to the direction in which the ratchet Wheel 8 is to be rotated. The pawl IEI can also be placed in neutral position by turning the knob I5 whereby the pin I'I will be made to engage the said circumferential Wall of the head of the winding barrel ll, and thus pawl I will be kept out of engagement with the ratchet wheel 8 (Fig. 4). In the barrel 4 near its upper end are a plurality of spaced openings I9 any one 'of which may receive one end of a tommy bar 20. The upper end of the spindle I can be externally screwthreaded as at 2| to receive a tapped cap 23; the latter also has a plurality of spaced openings 24 in its circumferential wall to receive one end of the tommy bar 20 when it is not in use for 'the openings in the barrel 4. The under face of the cap 23 is flat and can be made to engage with the upper face of the barrel Il which is also at.

Below the collar 2 on the spindle I the latter can be journalled in a bearing bracket 26, which may be secured to a decking or other support by screw bolts or other suitable means. The eX- tended end of the spindle I below the bracket 26 can be slidably secured in a coupling 21 by a set screw 28. Another spindle 30 also can be slidably secured by a set screw 29 in the coupling 2I, the spindle 30 at its lower end being journalled in a bearing 3| and also a footstep bearing 32; both bearings 3l and 32 are within a gear casing 33. Keyed or otherwise suitably secured to the spindle 30 is a gear wheel 34 which can be made to mesh with a worm wheel 3'5 on a drive shaft 3E having bearing in the gear casing 33, the shaft 36 being connectible for rotation to any suitable power drive means.

In operation, when the capstan means are to be used for hauling-in purposes with associated power means, the pawl I0 is set so as to drive the barrel 4 with the spindles 3i) and I and alsocto prevent the barrel 4 with its gipsy wheel 3 running backwards; simultaneously the barrel 4 and gipsy wheel 3 will be operatively connected together and to the spindle I and the whole of the said three components-barrel 4, gipsy wheel 3 and spindle I-can be rotated by the power drive means 34 and 3E associated with the spindle 3) and the coupling means 2'I, 28 and 23. The barrel 4 can have wound thereon a suitable hauling rope. The gipsy wheel 3 can be used with any suitable hauling chain.

If the capstan means are to be operated manually the power is disconnected from the said power drive means so that the spindles 33 and I and the wheel 8 will be held stationary. Ihe barrel 4 with the gipsy wheel 3 can then be rotated on the fixed spindle I by arcuately manipulating the tommy bar 20 in association with any of the holes I9 of the barrel 4. In such operation the pawl I0 will permit clockwise rotation (as seen in Fig. 4) of the barrel 4 relative to the stationary wheel 8; but, as long as the pawl I0 engages the recesses in the wheel 8, it will prevent backward running of the barrel 4 and gipsy wheel 3.

For running-out purposes of the hauling rope or chain, the power means before mentioned remain stationary; the pawl I0 is also placed in neutral position (Fig. 4) thereby operatively disconnecting the barrel 4 and gipsy wheel 3 from the spindle I, the latter remaining stationary. To enable manual control of the speed of the barrel 4 and gipsy wheel 3 during running-out operations, the tommy bar 20 can be inserted in one of the openings 24 in the cap 23 and the latter can thus be readily screwed down by arcuate manipulation of the bar 20 upon the upper surface of the barrel 4, the contact of the bottom surface of the cap 23 with the Lipper surface of the barrel 4 serving as clutch and brake means for the barrel 4 and gipsy wheel 3.

When it is desired to use the capstan means without power means associated therewith (Fig. 6), the spindle I at its lower end can be screwthreaded to receive a cooperative nut 39 whereby the spindle can be rigidly secured in a bracket CII 33. There is also an opening 3'I in the collar 2 which is adapted to receive a dowel pin 4E! which is rigidly alxed to the upper portion of the bracket 38. The barrel 4 with its gipsy wheel 3 is rotatable on the iixed spindle I by inserting the tommy bar 23 into any one of the openings I9 .in the winding barrel 4 and arcuately operating same. In such operation the pawl I0 is out of engagement with the wheel 8 but to prevent backward running of the barrel 4 and gipsy wheel 3 the pawl I0 is placed in engagement with the wheel 8. Clutching and braking of the barrel 4 and gipsy wheel 3 can be effected as beforementioned by operating the cap 23 in relation to the barrel 4 by using the tommy bar 23.

The bracket 38 can be secured to a ldecking or any other suitable support by screw bolts or other suitable means.

When the barrel 4 is removed from the spindle I the gipsy wheel 3 can be placed on the spindle I. Any gipsy wheel 3 of required chain pitch can be fitted to the spindle I by sliding any particular gipsy wheel 3 onto the spindle I and then replacing on the spindle I the barrel 4. Both the cap 23 and barrel 4 may be constructed of different metals.
